KVM: X86: Don't report L2 emulation failures to user-space
This patch prevents that emulation failures which result from emulating an instruction for an L2-Guest results in being reported to userspace. Without this patch a malicious L2-Guest would be able to kill the L1 by triggering a race-condition between an vmexit and the instruction emulator. With this patch the L2 will most likely only kill itself in this situation. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
